So I’ve been impatiently awaiting my results for 2 weeks now...was hoping to have them in by the end of last week since I was out of state for my brother’s wedding and wanted to announce with gender the day after. Anyways my results came in today that I need a redraw due to low fetal fraction!!! What makes this happen and who else has encountered this issue? Will I have to wait another 2 weeks now?!

the earlier in your pregnancy you draw the higher risk of inconclusive results due to low fetal fraction. After 12 weeks though you probably should've been okay. Sometimes women who are considered overweight also get inconclusive results until they are further along in gestation. Sometimes lab error can result in inconclusive results for example they shook the blood too fast and it coagulated, I know this because my lab told me they just had that happen with someone else as a tech was drawing my blood lol. Those are the only reasons I personally know of through research but there's probably more.

a little background I was 12w 6d when I did the test. I’m also 5’4” and 137lbs. The tech at the lab today was training a new girl on how to do the test and she said the sample tubes needed to be FULL FULL of blood, not just partly like most require so I’m wondering if there just wasn’t enough of a sample? Who knows but I’m totally bummed I have to wait another 2 weeks now!

when I was getting mine drawn it was a new girl that was being trained too. She messed up the one that got sent back before a o they were super watchful of her but she still had problems with mine. They thought it might get sent back, I was surprised it didn't. That might be what happened with yours!

oh gosh it’s an awful feeling after all that wait!! Did you get your results back yet?! I almost ordered sneak peek around a month ago and then decided I’d just wait for the panorama since my dr orders it anyways and it includes gender testing...now I wish I did the sneak peek so at least I’d know something by now!! Lol

I was 12w 5d with my now 9mo son when I tested last time and got my results in 5 days (Thursday-Tuesday), I never even considered that the results could take this long or come back inconclusive this time around! 😫

This exact thing happened to me. There are SOOOOOOO many factors as to why you could have low fetal fracture. Most common being a BMI of over 25 carries a low fetal fracture in general. The tech also could have not gotten enough blood or could have collected the test incorrect. Then there is the idea that you tested too early, or a low fetal fracture can be an indicator that is a genetic abnormality, but that is NOT the most common reason why. Also, some women just have a low fetal fracture. I retested and was able to get results. Good luck and fingers crossed!

This happened to me too. There wasn’t enough blood in the vials. I was so ticked that the phlebotomist didn’t collect more blood. Waited 2 weeks to hear they needed to redraw and then 2 more weeks to actually get results. Ugh. I won’t be using Natera for any other services.

Same thing happened to me with Natera. It was supposed to take two weeks. A day before the two week mark they called me and said I needed to redraw. So I did and they said it could take another two weeks for results but it only took one.

@Nancy11711 I did since I took the test around 13 weeks. They were very nice about it and shipped me a new kit free of charge and rushed the testing process once they received it! like literally had results within 4 hrs of them recieving the sample the second time! I was impressed! Results came back girl and they were right!

thanks for all the info! I definitely think it was due to the phlebotomist not filling the vials fully...I went to a different lab for the re-draw and they were adamant about getting them full so fingers crossed, this waiting game is the pits!

For any of you ladies on here who did a repeat Panorama...did they also do the “horizon carrier screen”? I went on the Natera website to make sure my sample arrived and it says the Panorama is pending but also that a “horizon carrier screen” was pending....my MD never discussed genetic screening with me so I’m just wondering if this is standard procedure when you have a test come up with low fetal fraction and also a history of miscarriage?? I’m confused and now worried

I was 9 weeks and 1 day with mine and everything came back fine. it was called a panorama. probably the same thing you're talking about. I think I got the results in 5 business days. way faster than I thought. I am waiting for the ultrasound to confirm but it's supposed to be a boy and my Dr said that if the test says it's a boy... then it's a boy lol so we will see.
